Why Does My Dryer Keep Shutting Off and How to Fix It

Ever been in the middle of drying your laundry, only to have your dryer suddenly stop working? Frustrating, right? Not only can this dampen your entire day (see what I did there), but it could also signal a larger problem with your dryer. In this post, we’ll explore why your dryer keeps shutting off and how you can fix it. We’ll walk you through the common causes, how to troubleshoot them yourself, and when to call in the pros. Let’s get started!

Your Dryer is Overheating

Dryers are built to shut off if they get too hot. Overheating can happen for a few reasons, like a blocked vent or a motor that’s too hot. To keep your dryer from overheating, follow these tips:

1. Clean the lint filter often. A dirty lint filter blocks airflow and makes the dryer overheat.
2. Check the ventilation. Make sure the vent tube or exhaust vent isn’t blocked.
3. Don’t overload the dryer. Too many clothes can cause the dryer to work harder than necessary.

Common Causes of Dryer Shutting Off and How to Troubleshoot

Tripped Circuit Breaker

Dryers are power-hungry beasts, and if they draw too much power, they trip the circuit breaker, cutting off power to the dryer. Here’s how to check your circuit breaker:

Find the Circuit Breaker Box. Go to your breaker box and look for the dryer’s switch.

Reset the Breaker. If the switch is off, turn it back on. If it turns off again, there might be a bigger electrical problem that will require a certified electrician to check it out.

Power Source Issues

A lousy power source is often the easiest but overlooked reason your dryer might shut off after a few minutes. Here are a few things to check:

1. Inspect the power cord. While less common, a damaged power cord can cause the dryer to shut off. Look for any signs of damage, like a frayed power cord. If the power cord is damaged, replace it with a new one.
2. Check the outlet. Sometimes, the outlet itself might be the problem. Use a multimeter to see if the outlet is providing the correct voltage. If it isn’t working correctly, you’ll need an electrician to repair or replace it to keep a steady power supply for your dryer.

Condenser Failure

Another common reason dryers shut off is because of a faulty condenser. The condenser’s job is to remove moisture from your clothes. If it’s not working, your dryer won’t work right. Here’s how to check if the condenser is the problem:

1. Check the tray. A full or blocked tray can stop the condenser from working. To avoid this problem, empty the tray and clean it regularly.
2. Check for blockages. Inspect the condenser for any debris or lint buildup.

If these steps don’t fix the problem, the condenser might be faulty. In that case, it’s best to call a professional to replace it.

Broken Drive Belt

A broken drive belt can cause your dryer to stop working mid-cycle. Here’s how to fix it:

1. Check if it is broken. You’ll need to open the dryer’s panel to find the drive belt. If the belt is worn out or broken, it will need to be replaced.
2. Replace a broken drive belt. Check the manufacturer’s manual to determine the type of belt you need and how to replace it.

Clogged Dryer Vent

A clogged dryer vent can cause overheating and make the dryer shut down. Here’s how to unblock it:

1. Check to see if your vent is blocked. Remove the vent hose from the back of the dryer and look for lint or debris.
2. Clean the dryer vent. Use a vacuum or a vent cleaning brush to remove lint or debris from the hose and vent cover.

The National Fire Protection Association (NFPA) recommends cleaning your dryer vent at least once a year. 

Overheating Dryer Motor

Your dryer’s motor works hard to turn the drum, and if it overheats, it will shut down for safety reasons. Here’s what you need to know:

1. How to check if the motor is overheating. If the dryer shuts off and feels unusually hot, the motor might be overheating. Let the dryer cool down, and then try rerunning it.
2. How an overheating dryer motor affects your dryer. An overheating motor can cause long-term damage. If it continues to overheat, it may need to be replaced.

Faulty Door Latch or Switch

The door latch’s job is to keep the dryer from running when the door is opened. The dryer might think the door is open and won’t run if it’s broken. Here’s how to check if your door latch is working correctly:

1. Inspect the door switch. Check if the switch is broken or not lining up. If it’s not keeping the door closed, you’ll need to replace it.
2. Replace your door latch. Read the manufacturer’s manual to find the right switch or latch for your dryer and follow the instructions to replace it.

Malfunctioning Moisture Sensor

The moisture sensor detects how wet your clothes are and tells the dryer when to stop.  If it malfunctions, the dryer might shut off before drying your clothes. Here’s how to check and replace the moisture sensor:

1. Check the moisture sensor. Find the sensor inside the dryer drum. Clean it with a soft cloth if it looks dirty.
2. How to install a new moisture sensor. If cleaning it doesn’t work, you’ll need to replace the sensor. Look for your dryer’s model number, visit your local home improvement store, and buy a new sensor.  If you’re uncomfortable installing it yourself, contact a professional appliance repair technician.

Dryer Maintenance

Maintaining your dryer helps prevent problems down the road.  Here are some simple tips to keep your dryer in good shape:

1. Clean the lint. Always clean the lint trap after every load. This helps maintain proper airflow and prevents overheating. Plus, lint buildup is a major fire hazard. Every year, clothes dryer fires account for an estimated 15,900 fires in the United States.
2. Inspect the vent system. Regularly check the vent hose and external vent cover for any blockages or lint buildup.
3. Check the Power Source: Make sure the power cord and outlet are in good condition to avoid power interruptions.
4. Schedule professional maintenance. To keep your dryer in top condition, have a professional technician service it once a year.

Following these tips can help your dryer last longer and work better, reducing the chance of unexpected shut-offs.

When to Call a Professional to Fix Your Dryer From Shutting Off

While many of these steps can be done on your own, some are best left to professionals. Here’s how to know when to call for help:

1. Dryer keeps shutting off: If your dryer keeps turning off, it’s time to get professional help.
2. Unusual noises: Strange sounds from your dryer mean you should call a professional appliance repair technician.
3. Burning smell: If you smell something burning, stop using the dryer and contact a professional right away.

Hiring a qualified appliance repair technician can save you time and prevent further damage to your appliance. Research certified technicians online and look for ones with good customer reviews. Ask friends or family for recommendations.
